Hi folks,this might sound strange, but is there a way to play this game open ended? I dont want any victory making the game stop. I just wanna keep playing. What settings would I have to start my campaign with?

From my limited experience, you can choose to continue playing after you obtain a Victory, though you'll have to put up with the "So-and-so obtained a 'blank' victory" text onscreen. Posted this in case you didn't already know that.
